Book excerpt: Moskowitz, Ooi, and Pedersen (2012) show that time series momentum delivers a large and significant alpha for a diversified portfolio of international futures contracts. We find that their results are largely driven by volatility-scaling returns (or the so-called risk parity approach to asset allocation) rather than by time series momentum. Without scaling by volatility, time series momentum and a buy-and-hold strategy offer similar cumulative returns, and their alphas are not significantly different. This similarity holds for most sectors and for a combined portfolio of futures contracts. Cross-sectional momentum also offers a higher (similar) alpha than unscaled (scaled) time series momentum.

Available in PDF, EPUB and Kindle. Book excerpt: While time series momentum is a well-studied phenomenon in finance, common strategies require the explicit definition of both a trend estimator and a position sizing rule. In this paper, we introduce Deep Momentum Networks -- a hybrid approach which injects deep learning based trading rules into the volatility scaling framework of time series momentum. The model also simultaneously learns both trend estimation and position sizing in a data-driven manner, with networks directly trained by optimising the Sharpe ratio of the signal. Backtesting on a portfolio of 88 continuous futures contracts, we demonstrate that the Sharpe-optimised LSTM improved traditional methods by more than two times in the absence of transactions costs, and continue outperforming when considering transaction costs up to 2-3 basis points. To account for more illiquid assets, we also propose a turnover regularisation term which trains the network to factor in costs at run-time.

Available in PDF, EPUB and Kindle. Book excerpt: Although portfolio management didn't change much during the 40 years after the seminal works of Markowitz and Sharpe, the development of risk budgeting techniques marked an important milestone in the deepening of the relationship between risk and asset management. Risk parity then became a popular financial model of investment after the global fina
Download or read book Time Series Momentum and Volatility States written by John Pettersson and published by . This book was released on 2014 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time series momentum returns are driven by volatility states. Controlling for standard risk factors, assets in a low volatility state produce positive and significant time series alphas, whereas high volatility state assets do not. Contrary to what is known about cross-sectional momentum, and to what behavioral models imply, time series momentum is most profitable in futures characterized by declining or low risk levels.

Download or read book Time Series Momentum written by Tobias J. Moskowitz and published by . This book was released on 2015 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: We document significant “time series momentum” in equity index, currency, commodity, and bond futures for each of the 58 liquid instruments we consider. We find persistence in returns for 1 to 12 months that partially reverses over longer horizons, consistent with sentiment theories of initial under-reaction and delayed over-reaction. A diversified portfolio of time series momentum strategies across all asset classes delivers substantial abnormal returns with little exposure to standard asset pricing factors and performs best during extreme markets. Examining the trading activities of speculators and hedgers, we find that speculators profit from time series momentum at the expense of hedgers.
Download or read book Scaling Clustering and Dynamics of Volatility in Financial Time Series written by Baosheng Yuan and published by . This book was released on 2008 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates volatility clustering, scaling and dynamics in financial series of asset returns and studies the underlying mechanism. We propose a direct measure of volatility clustering based on the conditional probability distribution (CPD) of the returns given the return in the previous time interval. We found that the CPDs of returns in real financial time series exhibits universal scaling, characterized by a collapse of the CPDs (of different time lags and of different returns in the previous interval) into to a universal curve exhibiting a power-law tail with an exponent of amp;−4. We construct a simple phenomenological model to explain the emergence of VC and the associated volatility scaling. We also study agent-based models of financial markets, and explore the impact of dynamical risk aversion (DRA) of heterogeneous agents on the price fluctuations. We found that the DRA is the primary driving force responsible for excess price fluctuations and the associated volatility clustering. Both our models (phenomenological model and agent-based model) are able to generate time series that reproduces stylized facts of the market data on different time scales. We have also studied general herding behavior often exhibited in financial markets in the context of an evolutionary Minority Game. We discovered a general mechanism for the transition from segregation into opposing groups to clustering towards cautious behavior.

Available in PDF, EPUB and Kindle. Book excerpt: The individual investor's comprehensive guide to momentum investing Quantitative Momentum brings momentum investing out of Wall Street and into the hands of individual investors. In his last book, Quantitative Value, author Wes Gray brought systematic value strategy from the hedge funds to the masses; in this book, he does the same for momentum investing, the system that has been shown to beat the market and regularly enriches the coffers of Wall Street's most sophisticated investors. First, you'll learn what momentum investing is not: it's not 'growth' investing, nor is it an esoteric academic concept. You may have seen it used for asset allocation, but this book details the ways in which momentum stands on its own as a stock selection strategy, and gives you the expert insight you need to make it work for you. You'll dig into its behavioral psychology roots, and discover the key tactics that are bringing both institutional and individual investors flocking into the momentum fold. Systematic investment strategies always seem to look good on paper, but many fall down in practice. Momentum investing is one of the few systematic strategies with legs, withstanding the test of time and the rigor of academic investigation. This book provides invaluable guidance on constructing your own momentum strategy from the ground up. Learn what momentum is and is not Discover how momentum can beat the market Take momentum beyond asset allocation into stock selection Access the tools that ease DIY implementation The large Wall Street hedge funds tend to portray themselves as the sophisticated elite, but momentum investing allows you to 'borrow' one of their top strategies to enrich your own portfolio. Quantitative Momentum is the individual investor's guide to boosting market success with a robust momentum strategy.
Download or read book Strategic Risk Management written by Campbell R. Harvey and published by John Wiley & Sons. This book was released on 2021-05-04 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: STRATEGIC RISK MANAGEMENT Having just experienced a global pandemic that sent equity markets into a tailspin in March 2020, risk management is a more relevant topic than ever. It remains, however, an often poorly understood afterthought. Many portfolios are designed without any thought given to risk management before they are handed off to a dedicated—but separate—risk management team. In Strategic Risk Management: Designing Portfolios and Managing Risk, Campbell R. Harvey, Sandy Rattray, and Otto Van Hemert deliver a reimagining of the risk management process. The book envisions a marriage between the investment and risk processes, an approach that has proven successful at the world’s largest publicly listed hedge fund, Man Group. The authors provide readers with a new framework for portfolio design that includes defensive strategies, drawdown risk controls, volatility targeting, and actively timing rebalancing trades. You will learn about how the book’s new approach to risk management fared during the recent market drawdown at the height of the COVID-19 pandemic. You will also discover why the traditional risk weighting approach only works on certain classes of assets. The book shows you how to accurately evaluate the costs of defensive strategies and which ones offer the best and most cost-effective protection against market downturns. Finally, you will learn how to obtain a more balanced return stream by targeting volatility rather than a constant notional exposure and gain a deeper understanding of concepts like portfolio rebalancing. Perfect for people working in the asset management industry and financial policy makers, Strategic Risk Management: Designing Portfolios and Managing Risk will also earn a place in the libraries of economics and finance scholars, as well as casual readers who take an active approach to investing in their savings or pension assets. PRAISE FOR STRATEGIC RISK MANAGEMENT “Strategic Risk Management shows how to fully embed risk management into the portfolio management process as an equal partner to alpha. This should clearly be best practice for all asset managers.” —Jase Auby, Chief Investment Officer, the Teacher Retirement System of Texas “This book shows the power of integrating risk and investment management, rather than applying risk management as an afterthought to satisfy set limits. I was pleased to shepherd some of the key ideas in this book through the publication process at The Journal of Portfolio Management.” —Frank J. Fabozzi, Editor, The Journal of Portfolio Management “Financial markets today are quite different from those of the last century. Understanding leverage, correlations, tails, and other risk parameters of a portfolio is at least as important as work on signals and alpha. In that sense, bringing risk management from ‘control’ to ‘front office’ should be a priority for asset managers. This book explains how to do it.” —Marko Kolanovic, Chief Global Market Strategist, J.P. Morgan A powerful new approach to risk management in volatile and uncertain markets While the COVID-19 pandemic threw the importance of effective risk management into sharp relief, many investment firms hang on to a traditional and outdated model of risk management. Using siloed and independent portfolio management and risk monitoring teams, these firms miss out on the opportunities presented by integrated risk management. Strategic Risk Management: Designing Portfolios and Managing Risk delivers a fresh approach to risk management in difficult market conditions. The accomplished author team advocates for the amalgamation of portfolio design and risk monitoring teams, incorporating risk management into every aspect of portfolio design. The book provides a roadmap for the crucial aspects of portfolio design, including defensive strategies, drawdown risk controls, volatility targeting, and actively timing rebalancing trades. You will discover how these techniques helped the authors achieve remarkable results during the market drawdown in the midst of the COVID-19 pandemic and how they can help you protect your assets against unpredictable—but inevitable—future bear markets. Ideal for professionals in the asset management industry, Strategic Risk Management: Designing Portfolios and Managing Risk is a valuable resource for financial policy makers, economics and finance scholars, and anyone with even a passing interest in taking an active role in investing for their future.
Download or read book Demystifying Time Series Momentum Strategies written by Nick Baltas and published by . This book was released on 2019 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motivated by studies of the impact of frictions on asset prices, we examine the effect of key components of time-series momentum strategies on turnover and performance. We show that more efficient volatility estimation and price trend detection can significantly reduce portfolio turnover by more than one third, without causing statistically significant performance degradation. We propose a novel implementation of the strategy that incorporates the pairwise signed correlations by means of a dynamic leverage mechanism. The correlation-adjusted variant outperforms the naive implementation of the strategy and the outperformance is more pronounced in the post-2008 period. Finally, using a transaction costs model for futures-based strategies that separates costs into roll-over and rebalancing costs, we show that our findings remain robust to the inclusion of transaction costs.

Download or read book Empirical Asset Pricing written by Wayne Ferson and published by MIT Press. This book was released on 2019-03-12 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the theory and methods of empirical asset pricing, integrating classical foundations with recent developments. This book offers a comprehensive advanced introduction to asset pricing, the study of models for the prices and returns of various securities. The focus is empirical, emphasizing how the models relate to the data. The book offers a uniquely integrated treatment, combining classical foundations with more recent developments in the literature and relating some of the material to applications in investment management. It covers the theory of empirical asset pricing, the main empirical methods, and a range of applied topics. The book introduces the theory of empirical asset pricing through three main paradigms: mean variance analysis, stochastic discount factors, and beta pricing models. It describes empirical methods, beginning with the generalized method of moments (GMM) and viewing other methods as special cases of GMM; offers a comprehensive review of fund performance evaluation; and presents selected applied topics, including a substantial chapter on predictability in asset markets that covers predicting the level of returns, volatility and higher moments, and predicting cross-sectional differences in returns. Other chapters cover production-based asset pricing, long-run risk models, the Campbell-Shiller approximation, the debate on covariance versus characteristics, and the relation of volatility to the cross-section of stock returns. An extensive reference section captures the current state of the field. The book is intended for use by graduate students in finance and economics; it can also serve as a reference for professionals.

Available in PDF, EPUB and Kindle. Book excerpt: A must-read book on the quantitative value investment strategy Warren Buffett and Ed Thorp represent two spectrums of investing: one value driven, one quantitative. Where they align is in their belief that the market is beatable. This book seeks to take the best aspects of value investing and quantitative investing as disciplines and apply them to a completely unique approach to stock selection.

This new investing strategy framed by the book is known as quantitative value, a superior, market-beating method to investing in stocks. Quantitative Value provides practical insights into an investment strategy that links the fundamental value investing philosophy of Warren Buffett with the quantitative value approach of Ed Thorp. It skillfully combines the best of Buffett and Ed Thorp—weaving their investment philosophies into a winning, market-beating investment strategy. First book to outline quantitative value strategies as they are practiced by actual market practitioners of the discipline Melds the probabilities and statistics used by quants such as Ed Thorp with the fundamental approaches to value investing as practiced by Warren Buffett and other leading value investors A companion Website contains supplementary material that allows you to learn in a hands-on fashion long after closing the book If you're looking to make the most of your time in today's markets, look no further than Quantitative Value.
Download or read book Trades Quotes and Prices written by Jean-Philippe Bouchaud and published by Cambridge University Press. This book was released on 2018-03-22 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread availability of high-quality, high-frequency data has revolutionised the study of financial markets. By describing not only asset prices, but also market participants' actions and interactions, this wealth of information offers a new window into the inner workings of the financial ecosystem. In this original text, the authors discuss empirical facts of financial markets and introduce a wide range of models, from the micro-scale mechanics of individual order arrivals to the emergent, macro-scale issues of market stability. Throughout this journey, data is king. All discussions are firmly rooted in the empirical behaviour of real stocks, and all models are calibrated and evaluated using recent data from Nasdaq. By confronting theory with empirical facts, this book for practitioners, researchers and advanced students provides a fresh, new, and often surprising perspective on topics as diverse as optimal trading, price impact, the fragile nature of liquidity, and even the reasons why people trade at all.

Available in PDF, EPUB and Kindle. Book excerpt: A one-of-a-kind reference guide covering the behavioral and statistical explanations for market momentum and the implementation of momentum trading strategies Market Momentum: Theory and Practice is a thorough, how-to reference guide for a full range of financial professionals and students. It examines the behavioral and statistical causes of market momentum while also exploring the practical side of implementing related strategies. The phenomenon of momentum in finance occurs when past high returns are followed by subsequent high returns, and past low returns are followed by subsequent low returns. Market Momentum provides a detailed introduction to the financial topic, while examining existing literature. Recent academic and practitioner research is included, offering a more up-to-date perspective. What type of book is Market Momentum and how does it serve a range of readers’ interests and needs? A holistic market momentum guide for industry professionals, asset managers, risk managers, firm managers, plus hedge fund and commodity trading advisors Advanced text to help graduate students in finance, economics, and mathematics further develop their funds management skills Useful resource for financial practitioners who want to implement momentum trading strategies Reference book providing behavioral and statistical explanations for market momentum Due to claims that the phenomenon of momentum goes against the Efficient Markets Hypothesis, behavioral economists have studied the topic in-depth. However, many books published on the subject are written to provide advice on how to make money. In contrast, Market Momentum offers a comprehensive approach to the topic, which makes it a valuable resource for both investment professionals and higher-level finance students. The contributors address momentum theory and practice, while also offering trading strategies that practitioners can study.

If you think those are the things to focus on in building an investment portfolio, Andrew Ang has accumulated a body of research that will prove otherwise. In this book, Ang upends the conventional wisdom about asset allocation by showing that what matters aren't asset class labels but the bundles of overlapping risks they represent.
